Manufacturers of these memory chips ensure that with every upgrade, they incorporate a power-saving component. The DDR4 consumes less power than the DDR3. The DDR4 has 12.75, as compared to the 12.5 nanoseconds latency of the DDR3. The difference in clocking speed does not, however, translate to a significant difference in the overall latency. The DDR4 can gain as much as 2133 MHz clock speed, which is much higher than the maximum 1066MHz for DDR3. The most obvious difference between these two chips is the clock speed. While both serve as virtual memory, they have many differences: Clock Speed Having seen the distinctive characteristics of the DDR3 and DDR4, let's make a direct comparison. This section is meant to offer you a visual representation of the two memory chips that you can take in and process at a glance. Now that we know what DDR3 and DDR4 are, let's see some of the key characteristics of these two memory chips. Relevant Characteristics Between DDR3 and DDR4 This is so because like all other DDR kits, it has a unique number and alignment of pins. You can only insert it into a slot made for DDR4 chips. It is worth noting that the DDR4 RAM module is neither backward nor forward compatible. This makes it one of the most sought after memory chips in the market today. However, this is made up for by the high performance and versatility that the changes have introduced, much to the joy of heavy computer users.
With the improvements on the DDR4 comes an increase in its price.
This is unlike the DDR3, which performs both a self-refresh and an auto-refresh on its content. The DDR4 memory performs a self-refresh to refresh its content. This makes it the most responsive DDR RAM on the market.Īnother improvement on the DDR4 is the reduced power consumption. It also has an excellent heat spreader that allows it to operate for long hours without overheating.
The DDR4-2400 is the smallest, while the DDR4-4400 has the highest speed and bandwidth.ĭDR4 is optimized for gamers, hence the elevated speed and bandwidth. Like the DDR3, DDR4 is offered with a range of specs. It has a larger capacity than its predecessors, the DDR, DDR2, and DDR3. What is DDR4?ĭDR4 is the fourth generation of DDR RAM to be introduced on the market. This is the lowest speed DDR3, and the highest in the DRR3-12800, with 1600 million per second bandwidth at 12800 MBps. DDR3-800 indicates that it has an 800 million per second bandwidth at 6400 MBps. Essentially, if you have a computer with a DDR3, it will process files twice as fast as a DDR2 equipped machine.ĭDR3 memory chips come in different specs depending on their speed. The DDR2 has a RAM speed of 3200 megabytes per second (MBps) while DDR3 can achieve 6400 MBps. The DDR3 uses about 30% less power and is two-times faster than its predecessor, the DDR2.
